创建存储过程test
CREATE PROCEDURE test ()
BEGIN
  update examinfo SET endtime = now() WHERE id = 14;
END;
创建event e_test
create event if not exists e_test
on schedule every 30 second
on completion preserve
do call test();
每隔30秒将执行存储过程test,将当前时间更新到examinfo表中id=14的记录的endtime字段中去.
关闭事件任务
alter event e_test ON
COMPLETION PRESERVE DISABLE;
开户事件任务
alter event e_test ON
COMPLETION PRESERVE ENABLE;
